Abstract
The utility model relates to a sealing ring with anti-rotation grooves. The sealing ring comprises a pedestal (1) and an annular step surface (2). The pedestal (1) and the annular step surface (2) are molded to be a whole structure. The annular step surface (2) is arranged above the pedestal (1). The annular step surface (2) and the pedestal (1) are coaxial. The annular step surface (2) is equipped with a main shaft hole (3) in a direction of the axis. Multiple anti-rotation grooves (4) are evenly disposed in the outer rim of the pedestal (1). Multiple spring mounting holes (5) are evenly arranged in the upper transverse plane of the annular step surface (2). The advantages of the utility model are that the sealing ring has a simple structure, the pedestal is equipped with grooves having arc surfaces so that positioning is achieved, the sealing ring is prevented from rotating and then is effectively prevented from offsetting during a mounting process especially a fastening process, and thus mounting is more convenient and easier; and friction imposed on the transverse plane of the sealing ring is reduced when the sealing ring is restricted by the anti-rotation grooves, and thus the service life of the sealing ring is effectively prolonged.
Description
Technical field
The utility model relates to a kind of sealing configuration, particularly a kind of seal ring with anti-rotation groove.
Background technique
Seal ring in the course of the work, except bearing the factors such as working temperature, pressure, corrosion, also need the friction pair end face friction of bearing due to seal ring to produce certain temperature simultaneously, thereby aggravated the wearing and tearing of the friction pair end face of seal ring, and then affected sealing effect and the working life of seal ring.
In mechanical system, seal arrangement is very important constituent element, under many circumstances, sealability will directly affect service behaviour and the quality of whole system, seal ring is generally used on the junction surface of the link of establishing stream in two, when seal ring is installed, need to be by seal ring inlay card in the adjacent groove that needs sealed connection part, then by bolt etc., two parts are connected, the sealing that keeps two links by seal ring, but such seal ring is easy to drop out when internal high pressure, and easily dislocation when mounted, cause sealing influenced, also may the internal flow path of link be formed and be disturbed simultaneously, give to install and use and bring very big inconvenience.
Model utility content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of seal ring with anti-rotation groove of simple in structure, easy for installation and difficult dislocation is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of seal ring with anti-rotation groove, it comprises base and annular table terrace, base and the annular table terrace structure that is formed in one, annular table terrace is arranged at the top of base, annular table terrace is coaxial with base, and offers spindle hole along axial direction; On the outward edge of described base, also evenly offer a plurality of anti-rotation grooves; On the upper-end surface of described annular table terrace, evenly offer a plurality of spring mounting holes.
Described spring mounting hole is blind hole, and the degree of depth of spring mounting hole is less than the height of annular table terrace.
Described anti-rotation groove is that one end is with the rectangular recess of arc surface.
The utlity model has following advantage: the utility model is simple in structure, on base, offer the groove with arc surface, realize and locate and limit seal ring rotation, in the time of can effectively avoiding installing, seal ring dislocation in especially fastening process, easier for installation, simple; Seal ring is under the restriction of anti-rotation groove, and the suffered friction of its end face reduces, the working life of effectively having improved seal ring.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A sectional structure schematic diagram in Fig. 1;
In figure: 1-base, 2-annular table terrace, 3-spindle hole, 4-anti-rotation groove, 5-spring mounting hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As depicted in figs. 1 and 2, a kind of seal ring with anti-rotation groove, it comprises base 1 and annular table terrace 2, base 1 and annular table terrace 2 structure that is formed in one, annular table terrace 2 is arranged at the top of base 1, and annular table terrace 2 is coaxial with base 1, and offers spindle hole 3 along axial direction; On the outward edge of described base 1, also evenly offer a plurality of anti-rotation grooves 4; On the upper-end surface of described annular table terrace 2, evenly offer a plurality of spring mounting holes 5.
Further, described spring mounting hole 5 is blind hole, and the degree of depth of spring mounting hole 5 is less than the height of annular table terrace 2.
Further, described anti-rotation groove 4 be one end with the rectangular recess of arc surface, during installation, by anti-rotation groove 4 restriction seal rings, circumferentially rotate, in use, seal ring end wear reduces simultaneously, has increased substantially the working life of seal ring.
